Análisis del deterioro de una señal de audio transmitida por radio frecuencia analógico y digital en refuerzo sonoro

The radio frequency transmission systems (RFTS) analog and digital are an important part of the electroacoustic chain involved in a sound reinforcement.These systems provide a great versatibility for the excecution of designs. However, the information available about these systems is not completly clear. Therefore, a protocol has been designed and implemented to characterize audio transmiters bodypack type, allowing to evaluate the existence of deterioration of the signal transmitted. For this protocol the influence of variables is estimated for analog and digital RFTS; the variales taked into account are distance, transmission power, output level, sensitivity and gain. The analysis included represents a new tool for audio operators and sound engineers as it describes the behaviour of RFTS for different common configurations. The subjective perpective is common rule of thumb used for decision that involve RFTS, the protocol here presented will help professionals to make an objective assesment of the possible situations. At the end, the best conditions to characterize any audio RFTS type bodypack are shown
